This might be a stupid question......

How possible would it be to operate a large program (Photoshop CS3) from a zip drive?

Here is my situation: I am working a new job, and have access to a PC and the internet. However, I am not allowed to bring in a personal computer. Since my job will often have down time, we are allowing to surf "safe" sites for workplace.....or basically do anything "safe" by utilizing the given desktop.

So......what I'd really like to do is to have PS CS3 in a form that I can run it on that desktop without permanently installing it. Is this possible through a big zip drive? After thinking about it......I would assume it needs a processor to operate a program like that. How about an external HD? Or I am fuxored unless I can install it?

If you're looking for a basic photo editing app. PC Mag did a list of the top 100 websites of the year and they had an online photo editing website on there. It might be worth checking out if you can't figure out PS. Also, some U3 flash drives have photo editing software on them. Maybe you can also talk the admin into installing Paint.net.
